mtd-www: NAND-DATA: Added NAND support table

Included new NAND Flash support table. This table includes data about
various NAND chips as well as information about the MTD subsystem's
support for these chips. The table is provided in CSV format and is
sorted, formatted, and output to an HTML page via a Python script
(added to Makefile). New entries can simply be added as new rows in
the CSV document.

Note: I did not link this into the main site yet. I can follow-up later
if you'd like, or feel free to do so yourself.

Philip Rakity contributed to fixing the build script.
